Aga running too hot

[kevin.etmuk]

I have had a second fire valve installed in line to protect our boiler since this was installed our aga keeps running too hot and makes strange sounds

[TimW]

don't know about the fire valve, but the Aga bloke told me that fuel oil is very variable in quality and content. Is it just a new batch in the tank?

Thank you for the info. Is there a question in there?

you could turn the thermostat down?

Quick get a recorder and record it, might be the next no.1. Brian

I assume the Fire Valve is a manually resettable valve inline with the oil feed, measuring the temperature at some point in your Aga.

I'm wondering if he defeated the thermostat to prove operation and simply hasn't put it back to your normal setting.

That is good advice. And a burner will make some strange sounds if it is running at a different temp.
